CVE-2026-28376: Vulnerability in Grafana Grafana OSS
The Grafana Live push endpoint can be exploited to cause unbounded memory allocation by sending a large or streaming request body, potentially leading to out-of-memory conditions. An authenticated user with access to the Grafana Live API can trigger this issue.
AI Analysis
Technical Summary
The Grafana Live push endpoint in Grafana OSS versions 8.0.0 through 13.0.1 contains a vulnerability that allows an authenticated user with access to the Grafana Live API to send a large or streaming request body, causing unbounded memory allocation. This can lead to out-of-memory conditions, impacting availability. The CVSS 3.1 base score is 6.5 (medium severity), reflecting network attack vector, low attack complexity, required privileges, no user interaction, and impact limited to availability. No official remediation or patch is currently documented.
Potential Impact
An authenticated user can exploit this vulnerability to cause Grafana OSS to consume excessive memory, potentially leading to service disruption or denial of service due to out-of-memory conditions. There is no impact on confidentiality or integrity reported. No known exploits are currently active in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the Grafana Live API to trusted authenticated users only and monitor for unusual memory usage patterns. Avoid exposing the Grafana Live push endpoint to untrusted users.
